Reliability of Copvs Accounting for Margin of Safety on Design Burst - Bog af Pappu L N Murthy - Paperback

Reliability of Copvs Accounting for Margin of Safety on Design Burst - Bog af Pappu L N Murthy - Paperback

In this paper, the stress rupture reliability of Carbon/Epoxy Composite Overwrapped Pressure Vessels (COPVs) is examined utilizing the classic Phoenix model and accounting for the differences between the design and the actual burst pressure, and the liner contribution effects. Stress rupture life primarily depends upon the fiber stress ratio which is defined as the ratio of stress in fibers at the maximum expected operating pressure to actual delivered fiber strength. The actual delivered fiber strength..

Radical Islam's Western Foothold - Hugo Chavez and Hezbollah - Bog af Sam Pickell - Paperback

Hugo Chavez' strategy of embracing Iran in its quest to build an \anti-imperialist\ and anti-American coalition of nations has undoubtedly gained strength in recent years. Beyond the close ties between Venezuela and Iran due to the two countries' shared anti-American priorities, there are also many similarities between the basic ideologies of Chavez' Bolivarian revolution and Iranian revolutionary thought. The Lebanese group Hezbollah shares many of Iran's priorities and principles, and it receives..

Ditching Tests of a 1/18-Scale Model of the Lockheed Constellation Airplane - Bog af Lloyd J Fisher - Paperback

Ditching Tests of a 1/18-Scale Model of the Lockheed Constellation Airplane - Bog af Lloyd J Fisher - Paperback

Tests were made of a 1/18-scale dynamically similar model of the Lockheed Constellation airplane to investigate its ditching characteristics and proper ditching technique. Scale-strength bottoms were used to reproduce probable damage to the fuselage. The model was landed in calm water at the Langley tank no. 2 monorail. Various landing attitudes, speeds, and fuselage configuration were simulated. The behavior of the model was determined from visual observations, by recording the longitudinal decelerations,..

Russian Defense Reform - Current Trends - Bog af Irina Isakova - Paperback

Since the fall of the Soviet Union, the topic of Russian defense policy has not received great attention. The rebuilding of Russian military strength is a high priority of President Vladimir Putin, and one to which he and his subordinates have devoted considerable time and resources. Therefore, inattention to Russian defense policy is unwise and even dangerous because it causes us to overlook potentially major changes not only in Russian policy, but in international affairs more generally.

Preliminary Structural Design of Composite Blades for Two- And Three-Blade Rotors - Bog - Paperback

Preliminary Structural Design of Composite Blades for Two- And Three-Blade Rotors - Bog - Paperback

A computerized method has been developed to aid in the preliminary design of composite wind turbine blades. The method allows for arbitrary specification of the chord, twist, and airfoil geometry along the blade and an arbitrary number of shear webs. Given the blade external geometry description and its design load distribution, the Fortran code uses ultimate-strength and buckling-resistance criteria to compute the design thickness of load-bearing composite laminates. The code also includes an analysis..
